Discussion

Organization
As the name suggests, JUNOS Cookbook is organized as a series of recipes. Each recipe
begins with a problem statement that describes a common situation you might
face. After each problem statement is a brief solution that shows a sample router
configuration or script that you can use to resolve that particular problem. A
discussion section then describes the solution, how it works, and when you should
or should not use it.
I have tried to construct the recipes so that you can turn directly to the one that
addresses your specific problem and find a useful solution without needing to read
the entire book. If the solution includes terms or concepts you are not familiar with,
the chapter introductions should help bridge the gap. Many recipes refer to other
recipes or chapters that discuss related topics. I have also included a variety of references
to other sources in case you need more background information on a particular
subject.
The chapters are organized by the feature or protocol discussed. If you are looking
for information on a particular feature such as BGP, MPLS, or SNMP, you can turn
to that chapter and find a variety of related recipes. Most chapters list basic problems
first and any unusual or complicated situations last. But there are some exceptions
to this, such as where I have instead grouped related recipes together.
